He said: “We’re doing a lot of work with leaders, everyone from sergeants and above, to talk about what the future will look like. These changes will have an impact on people; it’s not easy, we’re very aware of that.”

A Met spokesman said : “An organisation facing the challenges of the Met needs a robust and strong leader. London deserves a world class police force and its leaders need to deliver this.

“Results, such as a fall in key crime areas, show that officers and staff within the Met are coming together to support the changes required, but there will always be some people who aren't happy. “
